Mid-stage Pokemon like Poliwhirl rarely see competitive play outside of special formats. It's a waypoint on the road to Poliwrath, which is where the real potential kicks in. An original Gen 1 pick. Sits at a decent but contested Speed tier.
Speed and HP carry most of Poliwhirl's stat budget. Sp. Atk's the obvious dump stat. Common in the wild and yields 2 Speed EVs. Follows a 1.06M XP medium-slow curve.
Although it has become capable of living on land, it spends its time in the water, where its prey, fish Pokémon, are plentiful.
Its health suffers when its skin dries out, so be sure to moisturize it diligently.
